Intercom Allow
You can enable or disable the phone to automatically answer an incoming intercom call. If
Intercom Allow is enabled, the phone will automatically answer an incoming intercom call. If
Intercom Allow is disabled, the phone will handle an incoming intercom call like a normal call
instead of directly rejecting it. Intercom Allow is enabled by default.
Note
Intercom Mute
You can mute or un-mute the phone’s microphone for intercom calls automatically. If Intercom
Mute is enabled, the microphone will be muted for intercom calls. If Intercom Mute is disabled,
the microphone will work for intercom calls. Intercom Mute is disabled by default.
Intercom Tone
You can enable or disable the phone to play a warning tone when receiving an intercom call. If
Intercom Tone is enabled, the phone will play a warning tone before answering the intercom call.
If Intercom Tone is disabled, the phone will automatically answer the intercom call without
warning. Intercom Tone is enabled by default.
Intercom Barge
You can enable or disable the phone to automatically answer an incoming intercom call while
there is already an active call on the phone. If Intercom Barge is enabled, the phone will
automatically answer the intercom call and place the active call on hold. If Intercom Barge is
disabled, the phone will handle an incoming intercom call like a waiting call. Intercom Barge is
disabled by default.
Note
To configure intercom features via phone user interface:
1. Press Menu->Features->Intercom.
Your administrator can set a period of delay time before the phone automatically answers
intercom calls. Contact your system administrator for more information.
To enable the phone to receive a new incoming call when it has an active call, make sure that call
waiting feature is enabled on the phone in advance. For more information, refer to Call Waiting
on page 120.
